Wafer Pattern Aluminium Bronze Butterfly Valve NBR Liner Aluminium Bronze Disc

This wafer-pattern butterfly valve is designed to deliver dependable performance in medium-pressure systems requiring strong corrosion resistance, compact installation, and reliable sealing. Constructed with an aluminium bronze body and disc, and fitted with a durable NBR (nitrile rubber) liner, this valve is well-suited to a wide range of industrial and marine applications.

Technical Data:

• Body and Disc Material: Aluminium bronze (commonly B148/C9500 or equivalent), offering excellent corrosion resistance, particularly in marine, brackish, or chemically sensitive environments
• Liner Material: NBR (nitrile rubber), known for its strong sealing properties and compatibility with water, oils, and mild chemicals; operating temperature range from -25°C to +100°C
• Connection Type: Wafer pattern designed to fit between standard PN10, PN16, or ANSI 150 flanges, allowing for quick and space-efficient installation
• Pressure Rating: Rated to PN16 across most standard sizes, making it suitable for a broad range of utility and process applications
• Temperature Range: Operates reliably from -25°C to +100°C, ideal for moderate temperature applications
• Available Sizes: Commonly stocked in sizes from DN50 (2") to DN300 (12"), with larger sizes available on request
• Actuation Compatibility: Includes ISO 5211 mounting pad, making it easy to retrofit with a manual gearbox, electric actuator, or pneumatic operator

Key Features:

• Corrosion-Resistant Design: Aluminium bronze components provide excellent longevity in corrosive environments, far outperforming standard cast iron or carbon steel options
• Secure Sealing: The NBR liner ensures consistent shut-off and smooth disc rotation, delivering leak-free performance in a range of fluid applications
• Compact Wafer Design: Ideal for space-limited installations, allowing mounting between flanges without the need for extended face-to-face dimensions
• Automation Ready: Compatible with both manual and automated operation, thanks to standardised top flange mounting
• Versatile Utility: Engineered to handle various industrial fluids, including clean water, saltwater, and light chemical mixtures

Typical Applications:

• Marine and offshore environments requiring non-ferrous valve construction
• Water treatment and distribution networks needing dependable mid-pressure isolation valves
• HVAC systems handling hot and chilled water with compact valve requirements
• Light industrial processing lines involving mild chemicals or lubricants
• Pumping stations and utility pipelines with space constraints or corrosion exposure

Summary:

The Wafer Pattern Aluminium Bronze Butterfly Valve with NBR liner offers a balance of strength, chemical compatibility, and installation efficiency. It is built for engineers who demand durability and flexibility, providing long-term reliability in demanding fluid systems. Whether you're upgrading an existing installation or designing for future automation, this valve delivers performance you can count on.
